Viewmodel re initialization while its not cleared after navigating between screens

Question

This is my bottom app bar : ShoppingCartPage-HomePage-ProfilePage-MyOrders-SettingsPage

And Two screens: CategoryItemPage - OfferItemPage ( i dont want to save their states)

navigation: HomePage -> CategoryItemPage - > ShoppingCart to add items in shoppingCart

and HomePage -> OfferItemPage -> ShoppingCart to add items too

fun NavHostController.navigateSingleTopTo(
    route: CurrentDestination,
    currentDestinationRoute: String
) = this.navigate(route) {
    // If the destination doesn't exist, pop up to the start destination
    popUpTo(currentDestinationRoute) {
        //inclusive = true this means in the backstack entry the old destination will be replaced by the new destination
        //inclusive = false this means the backstack entry will put the new destination at the top and below it will keep the old destination
        inclusive = true
        saveState = true
    }
    launchSingleTop = true
    restoreState = true
}

  FloatingButtonBar(onShoppingCartClick = {
                        navController.navigateSingleTopTo(
                            route = CurrentDestination.ShoppingCartPage(),
                            currentDestinationRoute = currentScreenDestination.toString()
                        )
                    })
                }
 BottomAppBar(

                    navController.navigate(
                        CurrentDestination.CategoryItemPage(categoryItems = categoryItems)
                    ){
                    popupto(CurrentDestination.HomePage){
                    inclusive = true
                    saveState = true
                        }

                    launchedSingleTop = true
                },
                onOffersClick = { offers ->
                    navController.navigate(
                        CurrentDestination.OfferItemPage(offers = offers)
                    ){
                        popupto(CurrentDestination.HomePage){

                        }
                })

CategoryItemPage:

 addToCard = { categoryItemCart ->
                    navController.navigate(
                        CurrentDestination.ShoppingCartPage(
                            categoryItemsCart = categoryItemCart, offerCart = OfferCart()
                        )
                    ) {
                        popUpTo(route = currentRouteDestination) {
                            inclusive = true
                        }
                    }

OfferItemPage:

navController.navigate(
                        CurrentDestination.ShoppingCartPage(
                            categoryItemsCart = CategoryItemsCart(), offerCart = offerCart
                        )
                    ) {
                        popUpTo(route = currentRouteDestination) {
                            inclusive = true
                        }
